Question

A Differentiate between the following:
Q.S 1. Synthesis reaction & a substitution reaction.
Electrolytic decomposition & photochemical decompos
3 Thermal decomposition & thermal dissociation.
4. Decomposition reaction & a double decomposition reaction
rispy 5. Neutralization reaction & a precipitation reaction.​

Answer 1

Answer:

A type of chemical change in which two compounds in a solution react to form two new compounds by the mutual exchange of radicals. Usually, a solid is formed as a result of the reaction.

These reactions are of two types: Precipitation reactions and Neutralisation reactions.

Precipitation reactions

The insoluble solid formed during double displacement reactions is called a precipitate. Reactions in which a precipitate is formed as one of the products are also called as precipitation reactions.

Sodium sulphate reacts with barium chloride to form barium sulphate and sodium chloride solution.

Na2SO4 (aq) + BaCl2 ----> BaSO4(s) + 2NaCl(aq)
